Abstract

Abstract

In order to study the stiffness of PSRC beam, two prestressed steel reinforced concrete frames ware tested.The text results of the average strains of this sort of beam are basically consistent with the hypothesis of plan section, whose load-deflection curves are close to three-section line.Based on the experiment, it is derived the stiffness formula of the PSRC beam by the stiffness stack method.After comparing the calculation results with test results of deflection.It is believed that this formula can accurately calculates the stiffness of PSRC beam and also a reference for the compilation of the PSRC code.
